Abstract
Description
- The present invention relates to an elevator consisting of an elevator car, which car is movable in an elevator shaft, and a counterweight, wherein the elevator car and the counterweight are connected by a supporting and driving means guided over deflecting rollers and the deflecting rollers are integrated in the elevator car or the counterweight, wherein a drive drives the elevator car and the counterweight.
- An elevator with a 2:1 cable guidance is shown in the European patent application EP 04004311.9, in which the deflecting rollers of the elevator car are integrated in the car floor or in the counterweight. The supporting and driving means is guided in the car floor through a floor channel. By comparison with a conventional car floor with deflecting rollers arranged underneath (lower blocks), the car floor is overall very low in height, which has a direct effect on the shaft pit depth. The height gained by the car floor can be saved in the shaft pit depth.
- A disadvantage of this known equipment is that the deflecting rollers, which are integrated in the elevator car or in the counterweight, together with the supporting and driving means running in represent a substantial risk for maintenance personnel.
- The present invention avoids the disadvantages of the known equipment and provides an elevator installation which is safer for maintenance personnel.
- The advantages achieved by the present invention are that the deflecting rollers of the elevator car as also the deflecting rollers of the counterweight do not represent unexpected sources of risk for maintenance personnel. The supporting and driving means (cable, belt) running in and running out at the deflecting roller is covered by the equipment according to the present invention. Moreover, the equipment according to the present invention prevents the supporting and driving means from being able to partly or completely leave the deflecting roller in the case of, for example, excessive accelerations or decelerations. Moreover, the equipment according to the present invention prevents dirt and/or objects from being able to get between deflecting rollers and supporting and driving means. The equipment according to the present invention is inexpensive to manufacture and can be mounted in a simple manner.
- The above, as well as other advantages of the present invention, will become readily apparent to those skilled in the art from the following detailed description of a preferred embodiment when considered in the light of the accompanying drawings in which:
